You can apply a low-pass filter to the data first, in order to remove the "noise".

Probably, there is already some module on CPAN that does it (look for Fourier transform or series). Otherwise, programming it from scratch should not be too difficult once you understand the maths behind ;-)

Once you have your data cleaned, looking for stability intervals would just be a matter of defining how to measure stability. For instance, you can set a maximum Y delta and search for intervals where delta_X > min_delta_X and delta_Y < max_delta_Y

In any case, make your data samples available to us so we can also play with them!
